Development of a System of Scintillation Detectors for Space Radiation Suppression in the Framework of the Experiment Aimed to Study dd-Fusion Reactions at Low Beam Energy (PolFusion)

The development of a system of scintillation detectors is presented for cosmic-ray suppression in the experiment aimed to study dd-fusion reactions at low beam energy (PolFusion). The goal of the PolFusion experiment, which is conducted at the Petersburg Nuclear Physics Institute (Gatchina), is to study the fusion reactions 2H(d, p)3H and 2H(d, n)3He with polarized initial particles at low energies in the range of 10–100 keV. The presented work includes the following stages: simulation of the central detector system of the experiment and the scintillation detector system, design and development of the scintillation detector system, and the results of test measurements on cosmic rays.
